Use the following formula to determinethe percentage voltage imbalance:% voltage imbalance= 100 xExample: Supply voltage is 460-3-60.AB = 452 VoltsBC = 464 VoltsAC = 455 VoltsAverage voltage === 457Determine maximum deviation from average voltage:(AB) 457 - 452 = 5 V(BC) 464 - 457 = 7 V(AC) 457 - 455 = 2 VMaximum deviation is 7 V.Determine percent voltage imbalance.% voltage imbalance = 100 x= 1.53%max. voltage deviation from average voltageaverage voltage452 + 464 + 45537457This amount of phase imbalance is satisfactory as it is belowthe maximum allowable 2%.Operation on improper line voltage or excessive phase imbalanceconstitutes abuse and may cause damage to electrical components.NOTE: If more than 2% voltage imbalance is present, contactlocal electric utility.3.8.3 - 220-Volt operationAll 220-240-Volt units are factory wired for 208 Volts. The trans-formers may be switched to 220-Volt operation by switchingthe red (220-Volt) wire with the orange (240-Volt) wire at theTB1-1 terminal for single-phase and TB1-3 for 3-phase.Fig. 13 - 50RHE typical single-phase line voltagepower connection13713CapacitorCircuit breakerConnector CCUnit power supply.
